Manufactured by Fabrique Nationale, one of the top leading arms companies of Europe, the P90 is FN's answer to NATO's request for a compact Personal Defense
Weapon system that will defeat armored targets, which in the modern battlefield is becoming more proliferous. A bullpup design, the P90 boasts complete ambidexterity, with ambidexterous fire selector, magazine release, and downward casing ejection. Most
unique about the
weapon is its 50-round magazine, mounted vertically parallel to the
barrel, the cartridges are actually rotated 90 degrees in the magazine before entering the chamber. This round, the 5.7 x 28
mm (a necked-down 5.56 x 45mm), is being touted as the answer to kevlar-wearing opponents, being able to pierce
48 layers of CRISAT from a range of 200 m. With a dual-composition steel/aluminum core, the 5.7 will tumble upon penetration of soft tissue, leaving deep cavities up to 2-3 inches. Despite this, the relatively
low muzzle energy and
mass of the 5.7 round sometimes prove unreliable in terms stopping power against unarmored targets, unlike the venerable .45 ACP, or even the 9
mm Parabellum.
